The second processor 520 may wake up by using the first processor 510 or the follow-up command recognizing unit 540 to process an operation related to the voice command. According to an embodiment, the second processor 520 may wake up in sequence or in parallel with the wake-up of the follow-up command recognizing unit 540. The second processor 520 may have the same or similar structure as the processor 210 of FIG. 2 or the processor 480 of FIG. 4. According to an embodiment, the second processor 520 may be implemented with an Application Processor (AP).

For example, the processor 480 may be implemented with the first processor 510 (e.g., the wake-up processing unit 530) for recognizing the voice call command, a third processor (e.g., the follow-up command recognizing unit 540) for recognizing the follow-up command, and the second processor 520 for overall processing related to the follow-up command. According to an embodiment, the first processor 510 and the follow-up command recognizing unit 540 may be implemented with an additional chip (e.g., an wake-up engine, an ASR engine) capable of processing an operation related to voice recognition (e.g., a voice call command, a follow-up command), and the second processor 520 may process an operation related to execution of a function corresponding to the voice command on the basis of recognition of the voice command.

Although not shown, according to various embodiments, the second processor 520 may include a score processing unit (not shown) for calculating a recognition score for a voice call command, and a shared processing unit (not shown) for sharing the score with an external device (e.g., a different electronic device, a server), a command decision unit (not shown) for determining (or deciding) whether to execute the voice command on the basis of collected information (e.g., a score, a voice recognition result, etc.).

As shown in FIG. 5C, according to various embodiments, functions of the first processor 510 for recognizing the voice call command and the second processor 520 for recognizing the follow-up command may be implemented by one processor. For example, the first processor 510 may include the wake-up processing unit 530 and the follow-up command recognizing unit 540. The second processor 520 may process an operation related to the voice command after waking up on the basis of the first processor 510.

Although not shown, according to various embodiments, it can be implemented to recognize the voice call command and the follow-up command by using one voice recognition engine (e.g., the first processor 510 or the wake-up processing unit 530), instead of additionally implementing (or adding) the follow-up command recognizing unit 540 for recognizing the follow-up command.

According to various embodiments, the aforementioned various implementations of the first processor 510 for recognizing the voice call command and the second processor 520 for recognizing the follow-up command after waking up on the basis of recognition of the voice call command of the first processor 510 may be divided or integrated according to a device type (or feature) of the electronic device 400. For example, according to a device type based on power consumption, the first processor 510 and the second processor 520 may be implemented independently or may be implemented in a form of one chip.

According to an embodiment, if the electronic device 400 is a device to which power is always connected such as a refrigerator, an air conditioner, a television, or the like, it can be implemented by a single processor without having to add a separate chip (e.g., the second processor 520) for processing the follow-up command.

According to an embodiment, if the electronic device 400 is a device which uses a high-capacity battery such as an automotive infotainment device, it can be implemented by a single processor without having to add a separate chip for processing the follow-up command.

According to an embodiment, if the electronic device 400 is a device which uses a low-power battery such as a smart phone, a watch, a Bluetooth speaker, or the like, a low-power chip (e.g., the second processor 520) capable of recognizing a command may be added in addition to the first processor 510. Alternatively, according to various embodiments, the electronic device 400 may be designed such that both the voice call command and the command can be recognized while using one low-power chip (e.g., the first processor 510 or the second processor 520).

TABLE 3 Name (nickname, device Domain Account Category identifier) Score (command) First account Phone Galaxy 400 phone message music . . .

According to various embodiments, the first electronic device 710, the second electronic device 720, and the third electronic device 730 may perform transmission to the server 750 by including only a name for device identification and a calculated score.

Upon receiving service information from the first electronic device 710, the second electronic device 720, and the third electronic device 730, the server 750 may decide a target device for executing a voice command on the basis of the score of the first electronic device 710, the second electronic device 720, and the third electronic device 730. For example, the server 750 may decide (or determine) an electronic device (e.g., the second electronic device 720) having a highest score, and may determine the electronic device as the target device for executing the voice command. The server 750 may determine that an electronic device (e.g., the first electronic device 710, the third electronic device 730) other than the decided electronic device (e.g., the second electronic device 720) is to wait.

According to various embodiments, the server 750 may identify devices grouped with the same account, on the basis of service information for each device as shown in the example of Table 2. According to an embodiment, the server 750 may pre-register and manage service information as shown in the example of Table 1, and may change the service information as shown in Table 2 in response to reception of score information. According to an embodiment, upon determining an execution target device, the server 750 may initiate the score information in the service information.

In operations 815, 817, and 819, the server 750 may transmit a response (e.g., a first response, a second response) to the first electronic device 710, the second electronic device 720, and the third electronic device 730 on the basis of a decision result. According to an embodiment, the server 750 may transmit the first response to an electronic device (e.g., the second electronic device 720) determined as the execution target device to execute a voice command. According to an embodiment, the server 750 may transmit the second response to an electronic device (e.g., the first electronic device 710, the third electronic device 730) other than the execution target device to transition to a standby state.

According to various embodiments, the first electronic device 710, the second electronic device 720, and the third electronic device 730 may receive a response from the server 750, and may perform a corresponding operation on the basis of the received response. According to an embodiment, the first electronic device 710 and the third electronic device 730 may transition to the standby state in response to reception of the second response. According to an embodiment, the second electronic device 720 may perform an operation related to a voice command based on user's utterance, in response to reception of the first response.

Meanwhile, according to various embodiments, if a follow-up command is included as shown in the example of FIG. 8, the first electronic device 710, the second electronic device 720, and the third electronic device 730 may perform transmission to the server 750 by including service information and the follow-up command.

Upon receiving the service information and the follow-up command from the first electronic device 710, the second electronic device 720, and the third electronic device 730, the server 750 may decide a device capable of executing a command corresponding to the follow-up command. According to an embodiment, if the follow-up command is included, the server 750 may determine a device for performing an operation with reference to device information (e.g., a device name or a nickname, a domain list) among the first electronic device 710, second electronic device 720, and third electronic device 730 of the same account.

According to various embodiments, the server 750 may determine the execution target device by preferentially considering whether a command is executable based on the follow-up command with a higher priority than the score of first electronic device 710, second electronic device 720, and third electronic device 730. For example, even if a specific electronic device is determined based on the score, the server 750 may determine a different electronic device capable of executing a command as a target device. For another example, if the follow-up command is included, the server 750 may determine an execution target device by preferentially identifying whether the command is executable based on the follow-up command.

According to various embodiments, if the follow-up command includes a device designation command, the server 750 may identify a device based on a designation command among the first, second, and third electronic devices 710, 720, and 730 grouped with the same account. For example, on the basis of device information (e.g., a device name (or a nickname), a device identifier, etc.) of devices grouped with the same account, the server 750 may identify an electronic device having corresponding device information, and may determine the identified electronic device as a target device for executing a voice command.

According to various embodiments, the server 750 may identify a domain list and thus identify one or more devices capable of executing a command among the first, second, and third electronic devices 710, 720, and 730 grouped with the same account.

According to an embodiment, if it is decided that there is one device capable of executing the command, the server 750 may transmit a first response for executing a voice command to a corresponding device capable of executing the command among the first, second, and third electronic devices 710, 720, and 730 grouped with the same account. The server 750 may transmit a second response for transitioning to the standby state to a different electronic device not capable of executing the command.

According to an embodiment, if a plurality of (e.g., at least two) devices are capable of executing the command, the server 750 may determine a feedback target device on the basis of a score of corresponding electronic devices. According to an embodiment, the server 750 may determine an electronic device having a highest score among the plurality of electronic devices capable of executing the command as a device for feedback of the user 700. For example, the server 750 may provide the feedback to the user 700 to determine (or select) an execution target device for executing a voice command by using Text To Speech (TTS) or other methods or the like. According to various embodiments, the server 750 may transmit to a feedback target device (e.g., the second electronic device 720) a third response (e.g., a feedback response) to request for feedback, and may transmit to a different electronic device (e.g., the first electronic device 710, the third electronic device 730) a different response to wait for a response. According to an embodiment, the server 750 may transmit to the different electronic device a second response to transition to the standby state.

For example, referring to FIG. 8, it may be assumed that a domain associated with a follow-up command, i.e., a command of “play music”, is “music”. As shown in FIG. 8, it may be assumed that a domain “music” is included in a domain list in the first electronic device 710 and the second electronic device 720. In this case, the server 750 may determine the second electronic device 720 having a higher score between the first electronic device 710 and the second electronic device 720 as a feedback target device. Upon determining the feedback target device, as shown in operation 821, the server 750 may transmit a command (e.g., a feedback command) to the second electronic device 720 determined as the feedback target device to request for designation (or selection) of the target device for executing the command. According to various embodiments, when the feedback command is provided, the server 750 may provide information on a device (e.g., the first electronic device 710, the second electronic device 720) that can be selected (or selectable) according to the feedback command.

Upon receiving the feedback command from the server 750, the second electronic device 720 may provide a feedback for requesting the user to designate a device in response to the feedback command. According to an embodiment, as shown in operation 823, the second electronic device 720 may request the user to select a device for executing a music playback command such as “On what device do you want to play music? You can play music on your phone and TV.”. According to various embodiments, the second electronic device 720 may guide information on selectable devices on the basis of device information received from the server 750.

The user 700 may utter a voice for designating (selecting) a specific device in response to a device selection feedback of the second electronic device 720. According to an embodiment, as shown in operation 825, the user 700 may utter a voice for designating (selecting) the first electronic device 710 such as “phone” or “play music on phone” or the like. Upon detecting a voice input based on the utterance of the user 700, the second electronic device 720 may transmit the input voice information to the server 750.

Upon receiving a response (e.g., voice information) corresponding to the feedback command from the second electronic device 720, the server 750 may decide an execution target device on the basis of the received response. According to an embodiment, the server 750 may analyze the received response to determine the first electronic device 710 as a final execution target device on the basis of the received response between the first and second electronic devices 710 and 720 capable of executing a function (e.g., music playback) based on the voice command.

Upon determining the execution target device, the server 750 may transmit a first response to the determined execution target device to instruct to execute the voice command (e.g., music playback). According to an embodiment, as shown in operation 829, the server 750 may transmit the first response to the first electronic device 710. According to various embodiments, the server 750 may transmit a second response to an electronic device (e.g., the second electronic device 720, the third electronic device 730) other than the execution target device to transition to the standby state. According to various embodiments, the second response may be transmitted in advance and thus the third electronic device 730 may be in the standby state. Therefore, the server 750 may transmit the second response to the second electronic device 720, and may not perform response transmission to the third electronic device 730.

The first electronic device 710 and the second electronic device 720 may receive a response from the server 750, and may perform a corresponding operation on the basis of the received response. According to an embodiment, the first electronic device 710 may perform a function (e.g., music playback) corresponding to the voice command as shown in operation 831 in response to reception of the first response. According to an embodiment, the second electronic device 720 may transition to the standby state in response to reception of the second response.
